The Stage III twin screw supercharger system prototype has been fabricated and is now operational. We are now looking to manufacture the first production run with a batch size of 4 systems. Details of the system development can be found in a thread in these forums at

From the feedback we've recieved our current mindset is that the system should be released with a 3 inch pulley generating 6 to 7 lbs of boost. This seems to be the natural ballance where the engine with it's current compression ratio will generate the most power with the most efficiency. The 1600ax supercharger used in the system features only a 1 hp parasitic loss at cruise which means that highway fuel consumption will remain for the most part unchanged despite the ability to generate %40-%50 more power whenever the accelerator is pushed. Since it is a positive displacement system the power is there whenever the pedal is pushed so that true on the street performance and drivability gains are there not just peak hp dyno #'s.
The engine management included with the system has room to grow with the expectation that in the future race minded people will build engines with closed deck blocks and lower compression ratios. We can help anyone interested in doing this. The supercharger is also capable of producing lots of "boost" on an engine which is built for it. The svx engine is for the most part rock solid and can easily built for specificalliy for more boost although the parts to do so are all custom orders.
This thread is for those actually interested in ordering. If you are interested in a system please post your desires and questions here so that we can develop and produce exactly what you want. If you do not genuinely expect to be ordering one of the first 4 systems please utilize a seperate thread and refrain from participating in this one.
Those with obdII SVXii who are interested please join in. You will need to contact me directly before ordering but we will handle your orders as well.
